Flue Gas Butterfly Orifice Plate / Routing Ventilation Air / Flue Gas - Wolf CGG-1K-24 Installation And Operating Instructions Manual

Selection of the flue gas butterfly orifice plate
- Prior to installing the flue gas system, check using the
appropriate tables, which of the flue gas butterfly orifice
plates supplied should be used. This is subject to the length
of the balanced flue pipe.
Never exceed the maximum lengths specified
in the tables, otherwise incomplete combustion
may result.
If the CO content in the flue gas is higher than
300 ppm (free of air), remove the cause;
otherwise do not continue to operate the gas
fired boiler, as there would be a risk of flue gas
escaping, resulting in the danger of poisoning.
Wolf boilers are certified as one unit with the
original Wolf balanced flue system. Use only
original Wolf balanced flue systems. Using
alternative accessories can lead to incorrect
functions. Material losses and injuries cannot
then be prevented.
Calculating the flue length 60/100 mm
Calculated flue length = length of straight pipes + 1.0 m per 90° bend / tee + 0.5 m per 45° bend
General information:
From a length of 3 m upwards, we recommend the
installation of a condensate trap.
